It looks like Joey's handwriting if you compare it to the cheques he wrote also.
Note the similarities on the business card between the 6 and the 8 in the bottom number and in the crossed out number written underneath DAN at the top and the high downward stroke on the cross of the number 4. Also the h in Chase and Charles has a similar wave shape as it tails off.
I think it's just written on different days with info added.
I can’t believe I am now studying hand writing

Yes on closer inspection a lot of the letters and numbers match up.
Do we know why he was paying money to Chase’s girlfriend?
